Oh, building 'fictional universe' - of the sort you see in a lot of
science-fiction series and media with measurements, their own
history, technology & how it works, etc. Worldbuilding is fun.
I have two such conworlds - one is an alternate history (Russians
conquer Iran + Afghanistan during 'Great Game'. US annexes all of
North America, Second East Asia War, etc). Another one is a future
science-fiction esque space opera with massive space battles with
countries modeled off internet forums and sites.

1. Internet (what a 'marvelous' library of information and data for
all to access, for free or reduced prices. Why buy media when you
wan watch it on youtube or whatnot!)
2. Freedom ("freedom is the right of all sentient beings")
3. Food. Because you die otherwise
4. Liquid nourishment. Because again, you die otherwise (that
should be reversed - Fluids is more important haha!)
5. Science-Fiction. Because of the whole "scifi becomes
technothrillers becoming truth" thing. Cyberpunk is also awesome as
a sub-genre because it has hackers! And online gangsterism! And all
sorts of cool stuff you see people doing now (i.e. Julian
Assange/Wikileaks, 2007 Estonia cyberwars, etc)
6. Anime. Cause the art style is nice and the plots can be good
